I agree that it is an attempt at a broad mana distribution, but most of my decks are either mono or dual colored, so the idea was to attempt a deck with more variety. Dual colored decks are much easier and generally more reliable for consistent combos, but I wanted to challenge myself to create a deck with more varying possibilities, but still manage to forge a general unifying engine behind the deck as a whole. The idea with this deck is finds cards that fuel the modules engine, creating servos, generating energy, and buffing the little servos in the process. All while the modules reduce the cost of the heavy-hitting
Metalwork Colossus. The only thing I don't like about the colossus is that it's so plain of a spell. It doesn't have any unique abilities. I've even considered
Cultivator's caravan for this deck. Colorless spell, mana generator, can be used as an attacker/blocker if need be, and reduces the cost of the colossus. But verderous gearhulk almost seems more reliable here. He's large, not larger than the colossus, but his ability can fuel the module engine up to four times in one turn, potentially. But the colossus can return from the graveyard, so granted he's plain, he can be annoying and a big attacker regardless.
Gearseeker serpent was another good suggestion. If he had flying, that card would almost be a sure win to include. But summoning a 5/6 for potentially only 2 islands is attractive on it's own. Any input is greatly appreciated from any and all. Again, I am new to the game and to deck-building in general.
